SKATE.

Application filed July 3, 1922. Serial no. 572,458.

To alien/ 2.0172 2?may concern: Figure 10 is cross sectional view Be it known that I, lVILBiiR D. CRAwrcnn, through the plate 49 and the blade 51; a citizen of the United States, residing at Figure 11 1S a side elevation of another Scottsbluff, in the county of Scott's Bluff embodiment of my invention very much 60 and State of Nebraska, have invented cerlike Figure 1;

W This invention relates to skates, and par Figure 13 is a bob skate as in Figure 9.

' 17. In other words, the construction for supporting the rear end of the sole plate: is exactly the same as the means for sup-- porting the heel plate.

The forward end of the sole plate is. riveted to a'plate 25, which forward end extends downwardly, as at 26, and is pivoted at 27 to an angular link 28, the lower ends 3- of which are pivoted to the inward eXten-- sions of the angular irons l7.

It will be seen that the pairs of links and 23 have parallel motion and that ners of the skate are turned into inclined position to a vertical plane or into a position parallel to this vertical plane. This. construction permits the skater to incline his body and incline the blades of the skatein exactly the same manner as if a singlerunner was used, the edges of both blades: biting into the ice in the same manner that the. edge of one blade would do in the ordinary skate. lVhen the skaters body is inclined and the sole and heel plates are in-' olined to the horizontal. one blade does not leave the ice as it would were the blades fixed, but both blades engage the ice at the same time so that the blades follow and swing with the motion of the skaters body and permit all the necessary evolutions to be made.

InFigures 5 to 8 Ishow another embodiment of my invention, and in these figures 29 designates the runner, which is of common and ordinary form, each runner being provided with an upwardly extending portion 30 disposed adjacent the forward end and rear end of the runner. Each of these upwardly projecting portions is vertically slotted at two points at 31, and riveted to the ends of each portion 30 are the hinge beads 32 which are U-shaped in form and embrace the lugs formed by cutting away the middle portion of the upwardly extending member 30, as at 33. Pintles 34 extend through each pair of binge beads, and hinged to these pintles by means of the hinge leaves 35 are the trans versely extending plates 36 which are riveted to hinge leaves 35 by means of the rivets 37. These plates 36 are formed with iipwardly extending forward and rear lugs 38 perforated at 39. Riveted or otherwise attached to the portions 30 upon the inside faces thereof are pintles 40 disposed so as to intersect the slots 31 and these pintles pass through the ends of the angular links 42. The forward pair of links 42 are pivoted to a pair of arms or tongues 44 formed by bending down the ends of a plate 45 which is riveted or otherwise attached to the sole or heel plate of the skate. It will be understood that there are two of these plates 45. one at the heel and one at the toe, and that the parts 44 are the equivalents of the tongues or arms 19 in Figure 1. Pintles 43 and 46 pass through the arms 44, the links 42 and the upward-- ly extending lugs 38.

It will be understood that the plates 36 constitute in effect links and are in effect equivalent to the links 23 in the construction previously described. They, however. perform another function, in that they a t as holders tor rubber or other elastic blocks 47 through which the pintle 46 passes. These blocks fit between the upwardly extending lugs 38 and each block rests in a seat 49 riveted to the plate 36 and having upwardly extending ends, and at their up per ends these blocks rest in seats 50 having downwardly extending ends, these seats being constituted each by a plate riveted to the plate 45. This form of skate has the same advantages as the form previously described but with a certain additional function due to the elastic blocks 4-7 which tend to elastically resist the movement of the skate from a vertical to an inclined position and give a greater rigidity to the skate.

The form of skate body illustrated in Figure 5 is one wherein the body of the skate extends the full length between the heel and sole so that the heel plate and toe plate air. conjoined. The skate is illustrated as having a strap at the heel end whereby it may be engaged with the foot and a. clamp at the forward end to engage the sole of the shoe. Inasmuch as the body of the skate is of ordinary form no special description is necessary.

In Figures 9 and 10, I illustrate the application of my invention to an extensible skate. that is a skate wherein the body may be ad justed longitudinally to lit longer or shorter feet and wherein, therefore, two pairs of runners are used, one disposed beneath the toe l and one beneath the heel of the skate. In thi form of the device, each runner 51 is longitudinally slotted at its upper margin. as at 52, leaving a longitudinally extending pinlle 53 with which the plate 49 previously described is hingedly engaged by bending the ends of the plate around this pintle so that the ends of the plate form the hinge beads 54. Otherwise than this, this plate 49 is constructed precisely the same as the plate previously described. At the sole and heel are disposed the plates 45, as previously (l\- scribed, having the downwardly extending lugs 44 which are pivoted to the upwardly extending lugs 38 by the longitudinally exlUU tending pintle 46' which passes through. a which only two of these coacting arms and rubber buffer 47 in precisely the same man ner as previously stated. I have illustrated, however, only one angular link, which is designated 55. This 'link has its ends inserted in slots 56 and is pivoted upon pintles 5'7 riveted or otherwise attached to the inner face of each runner. This link is pivoted at its middle to the lower end of the arm 44.

. It will be seen that in this construction only a pair of links 55 are used in place of the two pairs of links 42 illustrated in Figure 7 but that the principle of operation is precisely the same as heretofore described and that thecushioning effect is the same. The skate is capable of the same evolutions as previously described'for the other skates, but in addition the skate is so constructed as to permit the body of the skate to be extended or contracted as desired. The body of the skate is of ordinary form and needs no special description.

In Figure 11, I have illustrated a skate of the same character as that shown in Figure 1 but differing from that shown in Figure 1 merely in the fact that the middle lug 16 with its attendant parts has been left off and the toe plate and heel plate are integral to form a foot plate which extends along the entire length of the skate. Otherwise than this, the skate illustrated in Figure 11 is precisely the same as that illustrated in Figure 1.

In Figure 12, I have illustrated a skate of the same form as that shown in Figure 5 but instead of having two levers 42 and two levers 44, I show only one lever 44 and one lever 42 at the rear end of the skate and one lever 44 and one lever 42 at the forward end of the skate. Otherwise than this, however, the construction is the same as that illustrated in Figure 5.

In Figure 13, the construction illustrated is the same as that in Figure 9, except that Figure 9 shows a single control comprising the downwardly extending lever or arm 44 and the angular lever 55. In Figure 13, however, I have shown two pairs of levers 55, one pair for each pair of runners 51 and two pairs of arms or levers 44 which engage with these levers 55. In other words, the construction shown in Figure 13 is precisely the same as that shown in Figure 9, except that a double control is illustrated instead of a single control.

The purpose of Figures 11, 12 and 13 is to illustrate the fact that the controlling elements may be either single or double on any one of the different forms of skate. It will be obvious, however, that the double control, that is the controls having four arms at tached to the body of the skate and extending downward to the runners, and four transversely extending angular levers, is a s ronger nd firmer construction than that in levers are provided.

I claim:

1. A skate having two runners and a body, the body having a plurality of downwardly depending arms, and a pair of links pivoted, at their iniddles to each arm at different heights, the ends of the links being pivoted to the runners at different heights whereby to cause the runners to tilt laterally in the same direction upon the tilting of the body.
